OPTIMIZATION OF HIGH-CONCENTRATION TRANS-ANETHOLE PRODUCTION THROUGH HYDRODISTILLATION OF STAR ANISE

A Comprehensive Review of the Pharmacology, Chemistry, Traditional Uses and Quality Control of Star Anise (Illicium verum Hook. F.): An Aromatic Medicinal Plant

Illicium verum Hook. F., also known as star anise, is one of the most important plants of the genus Anise in the family Magnoliaceae. I. verum not only has the functions of warming Yang, dispersing cold, regulating Qi and relieving pain but can also be used as a condiment to increase flavor as well as reconcile and remove fish smells. Currently, 201 chemical constituents have been identified from star anise; among these, star anise oil and shikimic acid are the two most widely used and studied chemical components in star anise, with the oil accounting for a large proportion of the total. This review integrates, classifies and updates studies related to the botany, pharmacology, phytochemistry, traditional and modern uses and quality control of star anise, with a special reference to its phytochemical composition and pharmacological activity. It will provide a reference for further research on this important medicinal plant. In addition, the broad applications and research profiles of star anise essential oil and shikimic acid are highlighted. Our review indicates that the research prospects regarding star anise are very broad and worthy of further investigation.

Cookies enriched with anethole and secoisolariciresinol diglucoside from flaxseed and fennel seeds improve hypercholesterolemia, lipid profile, and liver functions: A pilot study

Over millennia, flaxseeds and fennel seeds have captured greater attention owing to the broad spectrum of bioactive compounds and their respective therapeutic potential. They are well-known therapeutic plants, frequently used in home treatments for a variety of medical conditions. The novelty of this pilot study is to assess the beneficial health effects of secoisolariciresinol diglucoside (SDG) and anethole-based enriched cookies among hyperlipidemic patients. The result of sensory evaluation revealed that cookies with anethole and SDG (500 + 500 mg/day) were significantly acceptable in terms of color, texture, taste, and overall acceptability same as that of control. This study was performed among 34 patients with hyperlipidemia in a university-affiliated hospital, Lahore, Pakistan. In this study, patients received dietary supplementation with anethole and SDG (500 + 500 mg/day) administered in cookies for 8 weeks. Patients were assigned into two groups, intervention (receiving anethole + SDG-enriched cookies; n = 16) and placebo (n = 18), for 8 weeks. Both groups maintained the same diet and lifestyle. Pre- and postintervention weight, lipid profile, and liver enzyme levels were measured. Analysis of covariance and paired sample t-test were used for comparing the two groups. After 8 weeks, a significant mean weight loss was observed in the intervention group (4.26%) as compared to the placebo group (0.3%). A significant reduction of TC (177.02 ± 5.14 mg/dL; p = .024), TG (150.19 ± 7.94 mg/dL; p = .032), and LDL (87.38 ± 3.58 mg/dL; p = .001) were compared to the control group and HDL level (57.09 ± 3.90 mg/dL; p = .035) were increased in the intervention group as compared to the placebo. Meanwhile, it had a minor improvement in AST (30.97 ± 2.95 U/L; p = .01), ALT (33.05 ± 1.52 U/L; p = .025), and ALP (112.15 ± 4.03 U/L; p = .03) among the intervention group. Thus, based on the results from the study, it can be said that anethole + SDG-enriched bakery products could be developed as a functional dietary option for hyperlipidemia in developing countries like Pakistan.

Behavioral and Antennal Responses of Tribolium confusum to Varronia globosa Essential Oil and Its Main Constituents: Perspective for Their Use as Repellent

Essential oils of aromatic plants represent an alternative to classical pest control with synthetic chemicals. They are especially promising for the alternative control of stored product pest insects. Here, we tested behavioral and electrophysiological responses of the stored product pest Tribolium confusum, to the essential oil of a Brazilian indigenous plant, Varronia globosa, collected in the Caatinga ecosystem. We analyzed the essential oil by GC-MS, tested the effects of the entire oil and its major components on the behavior of individual beetles in a four-way olfactometer, and investigated responses to these stimuli in electroantennogram recordings (EAG). We could identify 25 constituents in the essential oil of V. globosa, with anethole, caryophyllene and spathulenole as main components. The oil and its main component anethole had repellent effects already at low doses, whereas caryophyllene had only a repellent effect at a high dose. In addition, the essential oil abolished the attractive effect of the T. confusum aggregation pheromone. EAG recordings revealed dose-dependent responses to the individual components and increasing responses to the blend and even more to the entire oil. Our study reveals the potential of anethole and the essential oil of V. globosa in the management of stored product pests.
